PRINTING PRESS Filed May 29, 1933 ATTOR N EYS Patented Aug. 28, 1934UNITED STATES PATENT GFFICE 2 Claims.

The invention relates to a printing press and more especially to a handoperated printing press.

The primary object of the invention is the provision of a press of thischaracter, wherein the construction thereof is for small jobs, forexample, show case cards, merchandise price cards or the like, requiringbut one or several for the respective merchandise or commodities, thepress being of novel construction to avoid the requirement of typesetting, framing or otherwise locking the type in the press andassurance of uniform pressure during the printing operation.

Another object of the invention is the provision of ,a press of thischaracter, wherein the type support is mounted in the bed of the pressat three-point connection therewith, while the platen is supported underuniversal connection with the operating lever therefor. Thus theprinting from the type can be carried forth uniformly and with dispatch.

A further object of the invention is the provision of a press of thischaracter, wherein the setting of the type can be carried forthexpeditiously and likewise the printing therefrom had with dispatch, thepress being designed for small jobs, such as show case cards, pricememoranda for merchandise, small exhibitor signs, plaques or the like.

A still further object of the invention is the provision of a press ofthis character which is extremely simple in construction, thoroughlyreliable and efficient in its purpose, readily and easily operated,strong, durable, and inexpensive to manufacture.

With these and other objects in View, the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described in detail, illustrated in theaccompanying drawing, which discloses the preferred embodiment of theinvention, and pointed out in the claims hereunto appended.

In the accompanying drawing:

Figure l is a side elevation partly in section of a press constructed inaccordance with the invention.

Figure 2 is a top plan view.

Figure 3 is a sectional view on the line 3-3 of 50 Figure 1.

Figure 4 is a sectional view on the line 4-4 of Figure 1.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawing.

Referring to the drawing in detail, the press constituting the presentinvention comprises a bed orbase 10, preferably in the form of an opensubstantially rectangular-shaped frame made from metal, although it canbe made from other material and solid if found desirable. At one end ofthe frame and medially thereof is a bracket 11 formed with double pintleeyes 12 accommodating a pintle or pivot 13 which engages the pintlesleeve end 14 of an operating lever or arm 15 adapted to overhang thebed or base 10. This lever or arm 15 at its pivot or pintle end is bentdownwardly at right angles to provide sumcient space between the bed orbaselO and the lever or arm 15 when in lowered position forthe occupancyof such space 0 by the equipment hereinafter described in detail.

'Detachably mounted upon the frame 10 is a type supporting'table or rest16 in'the form of a smooth flat plate having the depending legs or ears17, there being two at one side and one at the opposite side for athree-point connection of the rest 16 with the frame 10. These ears havepassed therethrough cotter pins 18 which are also engaged in suitableopenings in the sides of the frame 10 for the detachable fastening ofthe rest in position above the frame and perfectly level as shown inFigure 1 of the drawing. Upon this rest 16 are placed a group of type19, these under selection effecting the printing job, as for example,show case cards, merchandise price cards, exhibitor signs or work ofsmall kind. It is preferable to assemble the type 19 between spacerblocks or strips 20 although these are nonessential for a printing job,they being merely usable at the option of the operator of the press. Theprinting spaces of the type 19 are inked in any desirable manner, forexample, through the use of an inking roller (not shown).

Beneath the lever or arm 15 is a platen 21 which has formed thereincentrally thereof a bearing socket 22 for a universal fulcrum bearing 23carried by the lever or arm 15, while secured to this lever at oppositesides of the bearing 23 are leaf tensioning springs 24, these at theirends being secured to the platen 21 so that the said platen by itsfulcrum and under the action of the springs 24 will automatically adjustitself for a uniform pressure throughout the group of type 19 and a likeimpression on the work from the type 19. The matter to be printed iscarried by the platen 21 in any suitable manner at the impression sidethereof.

Embracing the platen 21 marginally is a coiled retractile spring 25which serves to hold a pad or covering 26 over the impression side ofsaid platen and this spring is held seated in grooves or channels 27therefor in opposite ends of the platen.

It will be apparent that by placing the cards or the like to be printedin place on the platen 21 at the impression side thereof and byoperating the lever or arm 15, the printing of such cards will takeplace when contacting with the group of type 19 upon the rest 16therefor and this contact is had by lowering the lever or arm 15 andexerting the required pressure thereon when contact of the card is hadwith the group of type 19.

It should be obvious that by reason of the length of the bed or base 10when the press is being operated, particularly on pressure applied tothe lever or arm 15, there is no liability of the press becoming tiltedas the bed or base will constitute a firm and solid foundation.

By the disposition of the fulcrum or bearing 23 centrally with respectto the platen 21 there is a direct and solid centralized pressure uponthe platen instead of the pressure being exerted through the springs 24or the equivalent as may be employed, the springs being for the purposeof holding the bearing 23 to its seat or in the socket 22, and also toassure unversal action of the plate with respect to; the confrontingtype upon the rest with a resultant uniform contact of the work withsaid type.

The lever or arm 15- at its hinged or pivoted end is right angularlybent downwardly, so as to have the said lever or arm for its majorportion elevated with relation to the plane of the rest 16 and to effecta raising of the platen with relation to the bed at the edges next tothe pivot or pintle13 instantly on the swinging of said lever or arm 15upwardly subsequent to the impression stroke thereof. In other words,when the lever or arm 15 has been raised to perpendicular position theangular portion of the same will offset the platen 21 with respect tothe rest 16 to relieve any interference after the setting of the typeupon said rest or the removal of the same therefrom and thus giving fulland free access to the rest.

By reason of the fact that both the rest 16 and platen 21 have extremelyaccurate surfaces and combined with the self adjustment'of said platenthis will allow the printing of any number of lines over a wide area byone impression and with very slight pressure.

What is claimed is:

1. In a hand printing press, an elongated bed, a type-supporting tablehaving depending perforated ears for a three-point connection with thebed,cotter pins engaged with the bed and said ears for the detachablemounting of the supporting table upon the bed, a hand operable leverbridging said table and having a downturned end, a bearing on the bedfor said downturned end of the lever, a pivot connecting the downturnedend with said bearing, and a selfadjusting platen carried by said lever.

2. In a hand printing press, an elongated bed, a type-supporting tablehaving depending perforated ears for a three-point connection with thebed, cotter pins engaged with the bed and said ears for the detachablemounting of the supporting table upon the bed, a hand operable leverbridging said table and having a downturned end, a bearing on the bedfor said downturned end of the lever, a, pivot connecting'the downturnedend with said bearing, a self-adjusting platen carried by said lever, a.center fulcrum on the lever for said platen, and leaf springs arrangedbetween the platen and said lever and engaged at its ends with saidplaten and intermediate thereof with said lever.
